Problems solved by technology

[0004] However, after a fiber failure occurs in the above-mentioned network, it is necessary to trigger each node to complete the cross-connection configuration hop-by-hop along the recovery path through the RSVP-TE signaling protocol. However, the cross-connection configuration takes a long time and each node is completed serially, resulting in failure recovery performance. Low

Embodiment Construction

[0068] In the solution provided by the embodiment of the present application, by pre-configuring the channel resources of each node of the preset recovery path, for example, the optical channel data unit (optical channel data unit-k, ODUk) time slot mapping of the line board, when the working path fails , the cross-connection of each node of the recovery path can be quickly established, so as to quickly restore the service. Since channel resources are pre-configured, the time spent on cross-connection configuration of each node during the fault recovery process can be reduced, and the service recovery performance can be improved. For its specific implementation, please refer to the specific explanations of the following examples.

[0069] First, some terms in the embodiments of the present application are explained, so as to facilitate the understanding of the service resource preconfiguration method in the embodiments of the present application.

[0070] ASON: It consists of...

Abstract

Disclosed in an embodiment of the present application are a service resource pre-configuration method, device and system. The method comprises the steps that after a first working path is established, a first node sends a first path message to a second node, wherein the first path message is used for indicating the second node to pre-configure a second channel resource, and the second node preconfigures the second channel resource according to the first path message. By implementing the embodiment of the invention, quick service automatic recovery can be realized, and the fault recovery performance is improved.

Description

technical field [0001] The present application relates to optical communication technology, and in particular to a service resource preconfiguration method, device and system. Background technique [0002] Automatically switched optical network (ASON) refers to the optical network connection within the optical transport network (OTN) or Synchronous Digital Hierarchy (SDH) transmission network under the control of the ASON signaling network The basic idea of ​​a new type of automatic switching network is to introduce a control plane into the optical transport network or SDH transmission network to realize the real-time on-demand allocation of network resources, thereby realizing the intelligence of the optical network. ASON has basically covered the metro and core backbone WDM networks. After a network fiber break, an end-to-end recovery path can be automatically established through the generalized multi-protocol label switching (GMPLS) protocol resource reservation protocol...
